TIRE BOLTER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 388,778, dated August28, 1888. Application filed May 10,1988. Serial No. 273,396. (No model.)

To aZZ whom it may concern.-

Be it known that .l, XVILLIAM A. JOHNSON, a citizen of the UnitedStates, residing at Aurora, in the county of Kane and State of Illinois,have invented new and useful Improvements in Tire-Bolters and Gutters,ofwhich the following is a specification.

My invention relates to an improvement in machines for bolting the tiresto vehiclewheels and cutting the projecting ends of the tire-bolt; andit consists in the peculiar construction and combination of devices thatwill be more fully set forth hereinafter, and particularly pointed outin the claims.

In the accompanying drawings, Figure 1 is a side elevation of atire-bolter and cuttinginaehine embodying my improvement. Fig. 2 is asimilar view of the opposite side of the same. Fig. 3 is a top planview. Fig. 4. is a front elevation.

A represents abasc-plate, which is adapted to be bolted to a suitablebench or horse on the upper side thereof, and is provided with a pair ofvertical standards, 13. To one end of the 2 5 base-plate is bolted asigmoidalshaped arm,O, which extends forward and laterally therefrom.

D represents a pair of rearwarddiverging arms, which extend from therear side of one 0 of the standards B, at a suitable distance above thebase-plate, and connecting the rear ends of the said arms is a loop orkeeper, E.

F represents a shaft, which is journaled in openings near the lower endsof the standards 5 B, and is arranged in a horizontal plane. The outeror front end of the said shaft is tapered and squared, as at G, toenable the same to be secured in the socket of an ordinary bit-stock,such as are employed by carpenters, wheel- 0 Wrights, and other workersin wood,andwhereby the shaft F may be rotated, as will be readilyunderstood.

A spur-wheel, H, is arranged between the standards B, and is featheredor splined on 5 the shaft F, so that the latter is free to slidelongitudinally in its bearings and through the wheel H. To the rear endof the shaft F is swiveled a socket or head, which is formed on thefront end of a rack-bar, I, that is arranged in the lower end of theloop or keeper E.

K represents a shaft, which is similar to the shaft F and is shorterthan the same, and is jonrnaled in openings near the upper ends ofstandards B. On this shaft K is feathered or splined a wheel, L, whichis arranged between the standards 13, the said shaft K being adaptedthereby to slide longitudinally through said standards and through saidwheel. The front end of the shaft K is provided with a movable head, M,that is seen red thereto by a set-screw, N, and has a socket, O, in itsfront end adapted to receive a nut to be applied to the spindle of atire-bolt. To the rear end of the said shaft K is swiveled a socketcdhead for the rack-bar P, which is ar- 6 ranged in the upper end of theguide orloop E.

R represents an idle-whecl, which is journaled in the loop or keeper 1?and engages the rack-bars, and is thereby adapted to cornmunicatelongitudinal motion from one shaft to the other.

On the outer end of the arm C is pivoted the lower end of a link, S,which has its upper end provided with a pair of cars, T, and has arecess, U, in its front side, at its upper end, in which recess isarranged a lower cutting jaw or blade, V, the upper edge of which isbeveled on opposite sides, the said jaw or blade being held intoposition in the link by a set-screw, W.

X represents a lever-arm, which is pivoted at its lower end, between theears T, on a bolt,

Y, and has a handle, Z, at its outer end. At the lower end of the arm Xis formed a shoulder or abutment, A, which is adapted to be en- 8 gagedby the head of an adjustable stop or bolt, B, which is screwed to theupper end of the link, so as to limit the motion of the arm X. A cuttingjaw or blade, 0, is secured to the outer side of the arm X, and issimilar to the lower jaw or blade, V.

The operation of mylnvention is as follows:

' The vehicle-wheel is journaled temporarily on a vertical spindle, a,that projects from the upper side of the bench or horse, so that thesaid wheel is disposed in a horizontal plane and is adapted to berotated. My improved machine projects up between two spokes of thewheel, with the shaft K on the level of the tire-bolt. of the tire-boltby hand until the nut is started, and the operator then attaches abit-stock to A nut is applied to the inner end 1C0 the outer end of thelower shaft, presses inward against the same so as to cause said shaft,by reason of the rack-bars and the idle gearwheel, to force the uppershaft outward until the socket-head of the latter receives the nut, andthe operator then rotates the lower shaft by means of the bit-stock, andconsequently imparts rotary motion to the upper shaft by reason of thegear-wheels, before described,

which connect the said shaft, and thereby drives the nut home on thebolt, as will be readily understood. Having secured the bolt, theoperator then draws outwardly on the lower shaft, so as to cause theupper shaft to move inward from and disengage the nut, the wheel ispartly turned so as to bring the bolt in the same vertical plane withthe link, and the handle-leverX is then grasped and swung upward andturned on its pivoted bolt, so as to cause the cutting-blades to openand receive the projecting ends of the bolt between them, and theoperator then draws outward on the upper end of the handle-lever, andcon sequently exerts such leverage on the cutting blades or jaws as tocause the same to completely sever the projecting end of the bolt.

Having thus described my invention, I c1aim- 1. The combination, in amachine for bolting tires, of the frame, the two shafts slidinglongitudinally therein and oppositelymovable, and gearing between thesame to impart a rotary motion from one to the other, one of said shaftshaving a socket adapted to receive the nut of a bolt, substantially asdescribed.

2. The combination of the base or frame having the standards 13, theshafts F K, journaled in said standards and movable longitudinally intheir bearings, said shafts having the rackbars, and one of said shaftsbeing provided with the socketed head, for the purposeset forth, thegear-wheel journaled in a suitable support and meshing with therack-bars, and,

the gear-Wheels feathered or splined on the shafts and meshing with eachother, substantially as described.

3. The combination of the frame or base,the link S, having one endpivotally connected to the frame and the other provided with a cuttingjaw or blade and an adjustable stop, and the lever X, pivoted to thefree end of the link and having a cuttingjaw or blade, substantially asdescribed.

4. The combination of the base plate or frame, the link S, pivoted orhinged thereto and having the adjustable stop D on one side and thecutting jaw or blade V on the opposite side at its free end, and thelever X, pivoted to the free end of the link, adapted to be engaged bythe adjusting stop or bolt, and having the cutting blade or jaw 0,adapted to operate in conjunction with the blade V,-

substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

WILLIAM A. JOHNSON.
